New parent pet peeve

I love when I haven't slept in over a month and I'm doing my best and my baby is being fussy (because he's a baby) and my mom will watch him for a half hour while I do stuff (she lives with me) and I'll go to grab him and she will say something like "Oh you said he was fussy but he wasn't at all with mee 🥰." Like why do you think you should say that, it makes me feel like a bad mom 😭. Rant over heres a picture of my baby boy cause I like to show him off 🥰
